Does 1Password not have a keyboard app for iOS 8? Keyboard apps in general are a pretty good way to get a lot of what people want from multi-window views on touch devices.
No they have an extension instead that people have been building into their apps that give one tap access to 1Password on the login screen. I suspect they stayed away from building a keyboard because it's a lot harder to get right, and to risk building a not-so-great keyboard to add one button didn't seem worth it.
No. Requires either a password to unlock the keychain or TouchID input. What the article completely misses is that there is window management in iOS. 5-finger pinch and all that. Not to mention the fact that a lot of iOS apps already have 1P integration so you don't have to leave the app.
